000 FZNT31 KNHC 150851 OFFN20 Marine Weather HF Voice Broadcast NWS National Hurricane Center Miami, FL 351 AM EST Wed Nov 15 2023 Marine Weather HF Voice Broadcast for the Tropical N Atlantic from 07N to 22N between 55W and 64W, the SW N Atlantic S of 31N W of 65W including Bahamas, and the Caribbean Sea. Seas given as significant wave height, which is the average height of the highest 1/3 of the waves. Individual waves may be more than twice the significant wave height. Synopsis for Caribbean Sea and Tropical N Atlantic from 07N to 19N between 55W and 64W .SYNOPSIS...Fresh to strong winds will prevail across the central Caribbean through late Thu. A broad area of low pressure is expected to form over the southwestern Caribbean this week. Environmental conditions appear marginally conducive for development of this system, and a tropical depression could form late this week while the system begins moving northeastward across the western and central portions of the Caribbean. Regardless of development, this system has the potential to produce heavy rains over portions of the Caribbean coast of Central America and the Greater Antilles through the end of this week. There is a medium chance of tropical cyclone development in the next 7 days. NW Caribbean W of 85W .TODAY...N winds less than 10 kt. Seas 3 to 5 ft. .TONIGHT...N winds less than 10 kt.

Fresh to strong NE-E winds prevail N of the front with seas to 10 ft. High pressure will continue to build in the wake of the front N of the area today. This will support an area of strong to near-gale winds over the waters N of 25N and W of 70W beginning tonight. A broad area of low pressure may develop over the waters W of 75W the second half of the week, with the strong to near-gale force winds shifting to the waters N of 27N and W of 70W toward the end of the week. Gale force winds are possible N of 27N Thu afternoon and Thu night, lifting N of 31N Fri afternoon. The low will drag a frontal boundary across the waters in its wake through the upcoming weekend.
